Large parrots (Macaws and cockatoos can live up to 80–100 years in captivity) Koi (A Japanese species of fish, allegedly living up to 200 years, though generally not exceeding 50 – A specimen named Hanako was reportedly 226 years old upon her death)[31][32] Tortoises (Galápagos tortoise) (190 years)[33] Tuataras (a New Zealand reptile species, 100–200+ years[34]) Eels, the so-called Brantevik Eel (Swedish: Branteviksålen) is thought to have lived in a water well in southern Sweden since 1859, which makes it over 150 years old.[35] It was reported that it had died in August 2014 at an age of 155.[36] Whales (Bowhead Whale) (Balaena mysticetus about 200 years) Although this idea was unproven for a time, recent research has indicated that bowhead whales recently killed still had harpoons in their bodies from about 1890,[37] which, along with analysis of amino acids, has indicated a maximum life span, stated as "the 211 year-old bowhead could have been from 177 to 245 years old".[38][39][40] Greenland Sharks are currently the vertebrate species with the longest known lifespan.[41] An examination of 28 specimens in one study published in 2016 determined by radiocarbon dating that the oldest of the animals that they sampled had lived for about 392 ± 120 years (a minimum of 272 years and a maximum of 512 years). The authors further concluded that the species reaches sexual maturity at about 150 years of age.[41]

Invertebrate species which continue to grow as long as they live (e.g., certain clams, some coral species) can on occasion live hundreds of years:

They're genetically immortal. They don't age and die, just continue growing bigger. Problem is that at a certain point moulting becomes so energetically demanding that they collapse half way through and starve to death.

I didn't know that. Probably the most interesting tidbit I've read in weeks

It's the same with jellyfish. They can revert to a polyp/salp phase and back to an adult phase technically forever. The sea really is so unexplored.

Thought that was the case. It's lucky that they're so delicious

Could be onto something, I recall on an episode of QI they were talking about how Galapagos Turtles were so delicious that Darwin's expedition took a bunch to study but ended up eating them on the way home.

It was worse than that. They were so delicious that none made it back for study, including ones caught by expeditions who's specific task was to bring them back home, entire, for study. For the best part of a century.

On a related note to this threadjack, if you're ever in London, the horniman's walrus is an interesting example of early science

Not all jellyfish, only the (somewhat appropriately named) Immortal Jellyfish. I learned so much from my kids watching Octonauts, including this.

Don't think that's completely true. That describes what's estimated to be around 15% of deaths, but in the remainder of "natural" deaths, the Lobster doesn't moult at all, the shell thickens and ultimately crushes the Lobster from the outside in.

That said, they're estimated to live between 50 an 100 years, and it's reckoned that they get more fertile qll the way through - randy old buggers
